LABEL DESCRIPTION
Active QoS Select the check box to turn on QoS to improve your network performance.
You can give priority to traffic that the LTE Device forwards out through the WAN
interface. Give high priority to voice and video to make them run more smoothly.
Similarly, give low priority to many large file downloads so that they do not reduce
the quality of other applications.
WAN Managed
Upstream
Bandwidth Enter the amount of bandwidth for the WAN interface that you want to allocate
using QoS.
The recommendation is to set this speed to match the interface’s actual
transmission speed. For example, set the WAN interface speed to 1000 kbps if
your Internet connection has an upstream transmission speed of 1 Mbps.
Setting this number higher than the interface’s actual transmission speed will stop
lower priority traffic from being sent if higher priority traffic uses all of the actual
bandwidth.
If you set this number lower than the interface’s actual transmission speed, the
LTE Device will not use some of the interface’s available bandwidth.
Leave this field blank to have the LTE Device set this value automatically.
Traffic priority
will be
automatically
assigned by These fields are ignored if upstream traffic matches a class you configured in the
Class Setup screen.
If you select IP Precedence or Packet Length and traffic does not match a class
configured in the Class Setup screen, the LTE Device assigns priority to
unmatched traffic based on the IP precedence or packet length.
